A good fit if…

  • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 52,000 BTU/h at 5°F.
  • You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

  • Cooling cost matters most - its SEER2 is below average for central heat pumps.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
